When and how to find a good property manager?

[Ahmad H.]

I have two multi-family rental properties and will soon have three. My goal is to buy one every six month. With each property the burden to manage and collect rents is growing and with a full time job I can see it getting stressful. I want to plan ahead on transferring this burden to a good property manager that will not cause me more stress with false repairs/bad tenants and whatever else that can happen. I would like some advice from those who have found a property manager and do not regret it. When should I start looking? Is it better to give them one property to test a manager or wait until I have 10 properties so I have more leverage? What questions to ask and what due diligence should I do when looking for a property manager? Thank you all for the great BP community!
